Description

  

  Verfahren zur Darstellung eines sauren     Farbstof%s    der     Antliraehinonreihe.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Darstellung eines  sauren Farbstoffes der     Anthrachinonreihe,     welches dadurch gekennzeichnet ist, dass man       1-amino-4-bi-omanthi,acliinon-2-sulfonsaures     Natrium     mitl-Amirio-3-inethylberizol-5-sulfoti-          siiuredioxäthylamid    kondensiert.

      <I>Beispiel;</I>    20 Gewichtsteile     1-Auiino-4-bromantlira-          chinon-2-sulfosaures    Natrium, 16 Gewichts  teile     1-Amino-3-methylbenzol-5-sulforisäure-          dioxäthylamid,    10 Gewichtsteile     Natriumbi-          carbonat    und 2 Gewichtsteile     Kupferchlorür     werden in 500 Gewichtsteilen     Wasser    bei  70   C 24 Stunden gerührt. Man erhält nach  der Isolierung und Reinigung einen klaren,  blauziehenden Farbstoff von sehr guter Lös  lichkeit und vorzüglichem     Egalisierungsver-          mögen.  



  Process for the preparation of an acidic dye of the anti-liraequinone series. The subject of the present additional patent is a method for the preparation of an acidic dye of the anthraquinone series, which is characterized in that 1-amino-4-bi-omanthi, acliinon-2-sulfonic acid sodium with 1-amino-3-ynethylberizole-5-sulfoti - Siiuredioxäthylamid condensed.

      <I> Example; </I> 20 parts by weight of 1-amino-4-bromantliraquinone-2-sulphonic acid sodium, 16 parts by weight of 1-amino-3-methylbenzene-5-sulforic acid dioxäthylamide, 10 parts by weight of sodium bicarbonate and 2 Parts by weight of copper chloride are stirred in 500 parts by weight of water at 70 ° C. for 24 hours. After isolation and purification, a clear, bluish dye of very good solubility and excellent leveling capacity is obtained.
